Older plows had a breakaway hitch, where the whole plow disconnected from the tractor if it hit a rock or other obstacle.

Then, there were trip plows, where just the bottom that hit an obstacle would trip back to avoid damage. You had to stop, and back up to reset the tripped bottom.

Then, of course, there are the more modern auto-reset plows on which a tripped bottom is automatically swung back into postion after the obstacle is passed by a heavy spring setup, or a hydraulic cylinder kept pressurized by a nitrogen-filled accumulator.
